2015 Top Solar Hot Water Contractors

Solar heating and cooling technologies collect thermal energy from the sun and use this heat to provide hot water, space heating, cooling and pool heating for residential, commercial and industrial applications.

The industry is dominated by PV, but solar hot water holds a strong presence in the residential market, and we want to accurately recognize those who work in both. The 2015 Top Solar Hot Water Installers list was determined by number of residential and commercial projects installed in 2014, not by BTUs or kilowatts. Contractors received one point per residential hot water installation and two points per commercial installation. The list may seem out of order, but when you take into account the number of projects each company installed, the ranking becomes clearer.
